- The front spoiler also he lps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­

Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the engine speed is below 1,SOO RPM . The begin­
ning of the red zone in the tachometer indicates
the maximum permissible engine speed for all
gears once the engine has been broken in and
when it is warmed up to operating temperat ure.
Before reaching the red zone, you shou ld shift in­
to the next higher gear, choose the Dor S selec­
tor lever position, or remove your foot from the
accelerator pedal.
CD Note
The needle in the tachometer @Q page 8,
fig. 3 may only be in the red area of the gauge
for a short time or there is a risk of engine
damage.
@ For the sake of the environment
Upshifting ea rly helps you to save fuel and re­
duces operating noise.
Fuel level
The fuel level indicator only operates when the
ignition is switched on.
The
tD ¢ page 15 turns on if the reserve quan ­
tity of fue l is reached.

Technical Data section ¢ page 210.
CD Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
Instruments and indicator lights
from that can cause engine misfires . Uncom­

tem. This can cause overheat ing and damage
to the catalytic converter.

On-Board Diagnostics
Fig. 5 Location o f Data Li nk Con necto r (OLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction , the com­
ponent will be identified and the fault sto red as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed (only vehicles with gasoline engine)
